ABSTRACT
Liners have been an essential component of modern municipal solid waste (MSW) and hazardous waste landfills for 20-30 years and more recently are becoming an essential component of many mining undertakings where applications include ponds for storage of liquids generated by mining, and liners for tailings dams and heap leach pads. Likewise, covers have been an important part of landfill design for decades. In mining, for many years there has been a recognized need for engineered covers for minimizing impacts due to acid generating waste rock however there is growing need for covers for other mine waste (e.g., arsenic bearing gold mine tailings).
